How to introduce Greenbelts to Cities Now

NASA satellite images show currently we pave about 20% to 40% of our cities to provide roads, parking lanes and service alleyways.

"Yet we are on the cusp of one of the fastest, deepest, most consiqential disruptions of transport in history." RethinkX think tank.

Using an electric ride share vehical will be four to ten times cheeper per mile than buying a new car if not in 2021, 2022/3, so fewer people will choose to buy and maintain their own vehicals. Privrate car ownership is expected to drop by 80% in the UK by 2030. As we move towards computer-controlled shared cars, we should see many fewer cars on the road; they will move more efficiently and traffic james (hopefully) will be a thing of the past. 

We will see fewer parked cars as the social conventions around the need for car ownership changes. According to the Buisness Insider Report in May 2017, cars sit parked more than 95% of the time. Once this inefficiency is addressed by shared cares constantly on the move, we will not need parking bays. We are already seeing the retrn to the bicycle as a healthier, inexpensive, non pollutring means of travel, further reducing the need for more cars and roadways.

Other developmens will be drone drop-offs to upper-story delivery ports. Also future emergancy response vehicals will have immediate access because smart cities will be able to shut off roads to accomodate them while GPS- controlled cars reroute themselves temporarily.

Why the contribution is important

As a result of all the above, its possible to imagin that tomorrow's urban roadway requirements will be reduced to smaller single lanes supporting a smooth local flow of traffic, likely all one-way streets, with few major arterial routes connecting city centers to each other. What this means is that we ought to be able to eliminate traffic on about half the roads and lanes we currently have, creating instantly available connected ribbons of space for greenbelts.

What might a road converted to a greenbelt look like? It maybe simply be a narrow road with low bushes planted on all sides forming headgerows to absorb sound and create safe barriers. In other areas, taller trees might be planted at the roads edges so that the tree canopy can connect across  the narrow roads like outside St. Ouen's Manor. Sidwalks can meander behind the headgrows and trees, further away from the cars.

This would be a fine example of conciouse planning and construction.

So, we can keep our indepenant transportation, save money and restore the ecosystems we depend on. While, incidentally, making the city a much nicer place to live.

    You make good points about greening our built up areas, but Jersey hardly really has a city!

    I think roads like Val Plaisant, the new Midvale Road, David Place, Belmont Road could all use more trees which could be implmented in the very short term.

    Trees could also be planted in between parking spaces e.g. outside the Market (maybe even down King Street).

    Out in the villages, all residential roads such as Ville des Chenes in St John, Les Quennevais Park St Brelade, could have more planters and trees.

    I think St Helier could be declared a Park Town - with a big focus on making beautiful and green public spaces.

    I think Gloucester Street, Route de la Liberation, Esplanade. I think more trees and planters around our roads would be great!
